The air outlet 23 of the hand dryer 22 is provided on the right side of the casing 16 with respect to the front surface 16a so as to protrude from the casing 16. The hand dryer 22 is provided with a human body detection sensor (not shown) in the vicinity of, for example, directly above the air outlet 23, and when the hand extended in front of the air outlet 23 is detected by the human body detection sensor, the hand dryer 22 is provided from the air outlet 23. Air is blown into the wash bowl 12 (that is, diagonally downward and forward). The wind from the blown air can dry your wet hands.

FIG. 2 is a perspective view showing the wash bowl 12 and its surroundings. In FIG. 2, a part of the washbasin 12 is shown semi-transparently. The inner surface (concave surface) 120 of the wash bowl 12 has a front surface portion 120a, a back surface portion 120b, a first side surface portion 120c, a second side surface portion 120d, and a bottom surface portion 120e. The first side surface portion 120c is the side surface portion of the two left and right side surfaces that is closer to the air outlet 23, and the second side surface portion 120d is the side of the two left and right side surface portions that is far from the air outlet 23. It is the side part of.

FIG. 3 is a horizontal sectional view of the washbasin 12. In FIG. 3, the position of the air outlet 23 is shown by a dotted line. The front surface 120a of the inner surface 120 of the wash bowl 12 has a portion 120aa facing the air outlet 23 in the front-rear direction in a plan view, in other words, a portion 120aa on the right end side of the front surface 120a from the first side surface 120c side. 2 The side surface portion is curved so as to be located on the front side toward the 120d side. The wind from the air blown out from the air outlet 23 hits the front surface portion 120a and is guided toward the second side surface portion 120d side far from the air outlet 23. As a result, it is possible to prevent the wind from the air outlet 23 from flowing out to the front side beyond the front surface portion 120a or to the right side beyond the first side surface portion 120c close to the air outlet 23. That is, it is prevented that the water attached to the inner surface 120 of the wash bowl 12 is blown out of the wash bowl 12.

FIG. 4 is a cross-sectional view taken along the line AA of FIG. FIG. 4 is a cross section cut in a vertical plane passing through the outlet 23. FIG. 5 is a cross-sectional view taken along the line BB of FIG. The front surface portion 120a of the inner surface 120 of the wash bowl 12 is formed so as to be convexly curved to the front side and the depth D becomes deeper from the first side surface portion 120c side to the second side surface portion 120d side.

Here, since the front surface portion 120a is curved, it can be considered that a flow path C extending to the left and right with the front surface portion 120a as a part is formed on the front side in the wash bowl 12. Since the front surface portion 120a is formed as described above, the flow path C has a larger cross-sectional area from the first side surface portion 120c side to the second side surface portion 120d side, and therefore the first side surface portion 120c side. The wind is more likely to flow from the second side surface portion to the 120d side. As a result, when the wind from the air blown out from the outlet 23 collides with the front surface portion 120a, most of the wind flows through the flow path C toward the second side surface portion 120d.

By guiding the wind from the air outlet 23 reaching the front surface 120a to the second side surface 120d side far from the air outlet 23 as described above, the wind from the air outlet 23 exceeds the front surface 120a and is on the front side. It is prevented that the air flows out to the right side beyond the first side surface portion 120c near the air outlet 23. That is, it is prevented that the water attached to the inner surface 120 of the wash bowl 12 is blown out of the wash bowl 12. The wind guided to the second side surface portion 120d side is attenuated while flowing to the second side surface portion 120d side.

The front surface portion 120a is preferably formed so that the degree of convex curvature to the front side decreases from the first side surface portion 120c side toward the second side surface portion 120d side. As a result, while increasing the cross-sectional area of the flow path C from the first side surface portion 120c side toward the second side surface portion 120d side, the thickness of the front wall portion 12a of the wash bowl 12 constituting the front surface portion 120a is relatively reduced. Can be thinned.

The wash bowl 12 has a barb 122 that projects rearward from the upper end of the front surface 120a. As a result, the wind from the air outlet 23 is prevented from flowing to the front side beyond the front portion 120a. The wash bowl 12 may have a barb that projects from the upper end of the first side surface portion 120c toward the second side surface portion 120d.

This embodiment is an example, and it will be understood by those skilled in the art that various modifications are possible for each of these components and combinations of each processing process, and that such modifications are also within the scope of the present invention. is there. Hereinafter, such a modification will be described.

In the embodiment, the case where the liquid discharge device 18 discharges the soap solution has been described. The liquid discharged by the liquid discharge device 18 is not limited to the soap liquid, and alcohol or other liquid for disinfecting the hands may be discharged.

In the embodiment, the case where the air outlet 23 is provided near the first side surface portion 120c on the right side of the two left and right side surface portions has been described. The air outlet 23 may be provided near the second side surface portion 120d on the left side. In this case, "right" and "left" may be interchanged and read.

The washbasin device 10 may further include an air curtain device 24 which is not mentioned in the embodiment. FIG. 6 is a vertical cross-sectional view of the washbasin device 10 according to the modified example, passing through the air outlet 23. Immediately above the air outlet 23 of the hand dryer 22, the air outlet 25 of the air curtain device 24 is provided so as to protrude from the casing 16. In particular, the air outlet 25 is provided so that the air blown from the air outlet 25 passes in the wash bowl 12 or directly above the air outlet 25 and passes above the front of the air outlet 23 of the hand dryer 22. That is, the air outlet 25 of the air curtain device 24 is provided so that the wind blown from the air outlet 25 passes above the hand dried by the hand dryer 22 substantially horizontally. A planar air flow is formed by the air blown out from the air outlet 25.

7 (a) and 7 (b) are diagrams for explaining the timing at which the air curtain device 24 starts blowing air from the air outlet 25. When the human body detection sensor of the hand dryer 22 detects a hand extended in front of the air outlet 23 of the hand dryer 22, the air curtain device 24 starts blowing air from the air outlet 25. The air curtain device 24 starts blowing air from the outlet 25 at a timing related to the timing when the hand dryer 22 starts blowing air from the outlet 23. Specifically, for example, in the air curtain device 24, as shown in FIG. 7A, the air outlet 25 is substantially simultaneously at the timing when the hand dryer 22 starts blowing air from the air outlet 23. You may start blowing air from. Further, for example, in the air curtain device 24, as shown in FIG. 7B, the air blown out from the air outlet 25 at a timing earlier than the timing when the hand dryer 22 starts blowing air from the air outlet 23. May start.

8 (a) and 8 (b) are diagrams for explaining the timing at which the air curtain device 24 stops blowing air from the air outlet 25. When the human body detection sensor of the hand dryer 22 stops detecting the hand, the air curtain device 24 stops the air blown out from the air outlet 25. The air curtain device 24 stops the air blowout from the air outlet 25 at a timing related to the timing when the hand dryer 22 stops the air blowout from the air outlet 23. Specifically, for example, in the air curtain device 24, as shown in FIG. 8A, the air outlet 25 is substantially simultaneously at the timing when the hand dryer 22 stops the air blowout from the air outlet 23. You may stop blowing air from. Further, for example, in the air curtain device 24, as shown in FIG. 8B, air is blown out from the air outlet 25 at a timing after the hand dryer 22 stops blowing air from the air outlet 23. May be stopped.

The air curtain device 24 may include a human body detection sensor different from the human body detection sensor of the hand dryer 22.

The planar air flow by the air curtain device 24 functions as a so-called air curtain, and prevents the water blown from the wet hands after washing by the wind from the hand dryer 22 from splashing out of the wash bowl 12.

The air supply source of the hand dryer 22 for blowing air from the air outlet 23 and the air supply source of the air curtain device 24 for blowing air from the air outlet may be common. In this case, since the number of parts is reduced, the cost of the washbasin device 10 can be reduced.

As a further modification, the air outlet 25 of the air curtain device 24 may be provided directly above the discharge port 19 of the liquid discharge device 18 so as to protrude from the casing 16. In particular, the air outlet 25 is provided so that the air blown from the air outlet 25 passes above the inside of the wash bowl 12 or directly above the air outlet 25 in front of the discharge port 19 of the liquid discharge device 18. May be done. That is, the air outlet 25 of the air curtain device 24 may be provided so that the wind blown from the air outlet 25 passes above the hand that is about to receive the liquid discharged from the liquid discharge device 18. In this case, the planar air flow by the air curtain device 24 prevents the liquid that bounces off by hand when receiving the liquid discharged from the liquid discharge device 18 from splashing out of the wash bowl 12.
